The Importance of Cummins Diesel Generator Crankshaft Oil Seal

Jul. 12, 2023

Shock absorber failure or poor sealing between Cummins diesel generator and generator, Cummins diesel engine failure shock absorber will increase the vibration of Cummins diesel generator. The crankshaft oil seal of Cummins diesel generator adopts dry seal, which must be a clean and dry place for installation and oil seal. It has never used oil to lubricate it so that the oil seal fails early. In addition, the front oil seal of Cummins diesel generator crankshaft is installed through self sealing bolts. If the tightening torque is incorrect, it may also cause leakage of bolt holes.

If rough stones or emery cloth are used to grind the crankshaft journal during major repairs, it will cause the surface area to be roughly the same, and the oil seal lip will be scratched during installation or operation. Crankshaft oil seal leakage is the comprehensive performance of Cummins diesel generator, rather than the multiple failures of simple seal failure. The oil seal can be squeezed, deformed, and damaged due to gaps between the axial and radial crankshafts, which can lead to oil seal leakage.

The vibration of Cummins diesel generator will be increased due to the faulty shock absorber of Cummins diesel generator, and the oil seal will be squeezed, deformed and damaged because of the axial and radial crankshaft with clearance, which will lead to oil seal leakage. There is a high requirement for the assembly environment of Cummins diesel generator. Cummins diesel generator is usually limited in the overhaul area of OT ground. Due to the poor assembly and assembly environment, oil leakage may occur.
